VULCANIZING APPARATUS Specification of Letters Patent.

Patented Aug. 3t, 1915.

' Application filed February 8, 1913. Serial No. 747,083.

To all whom it may concern Be it known that 1, CHARLES M. BEARDS- LEY, acitizen of the United States, residing at Cleveland, in the. county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in and Relating-to Vulcanizing Apparatus, of which thefollowing is a specification.

This invention relates to a vulcanizing apparatus.

It is particularly adapted for use in the repairing of tires, innertubes, and tire treads or shoes of rubber and for similar purposes.

One object'of my invention is to provide a simple, cheap and highlyefficient vulcanizer adaptable for quick repair service on bicycle,motor cycle, and motor car tires, tire parts and the like, and forsimilar purposes' Another object is to provide such a vulcanizer inwhich gasolene, alcohol or the like may be used for gas generating purposes, so constructed that the gases genermed will burn normally with ablue flame, indicating first class combustion.

Another object of my invention is to provide means for regulating andcontrolling the heat at or about the vulcanizing temperature to insuresatisfactory work.

Other objects" of my invention will be clear to one skilled in the artfrom a study of the construction and operation of the vulcanizers which,for the purpose ofillustration, I have, in the accompanying draw-,

ings, shown and herein described as embodying my invention.

Fig. 3 is a longitudinalsectional view through the 'vulcanizer and heat controller, the formerbeing clamped to a tire tube and in position for repairing it. Fig. 4 isa fragmentary view of a tire on a wheel and my vulcanizer and heatretainer fixed thereto for the purpose of repairing the tire. Fig. 5 isa perspective view, partly broken away, of afiame regulator orcontroller embodying a slightly modified form of my invention. P lg. 6is a fragmentary sectional view, somewhat enlarged,-showing thethermometer and its supporting members. Fig. 7 1s a perspective viewillustrating a modification of the invention. Fig. 8 is a longitudmalsectional view of the vulcanizer shown in Fig. 7 and a heat controller,the-latter being constructed to cooperate with the modified form ofvulcanizer.

' In the drawings, 1 indicates a vulcanizer arranged to engage with atire or other ar ticle A which is to be vulcanized or re paired. Thevulcanizer 1 comprises a bottom or vulcanizingplate 1 and inner andouter walls l 1, the latter coooperating with the bottom 1 to form a gasor fuel chamber 1. The bottom 1 is preferably concave in shape in orderto adapt it to the general shape of a vehicle tire. The walls 1?, 1, arepreferably of annular shape'and arranged concentrically with respect toeach other to form an annular shaped gas or fuel chamber. The outer wall1 may be arranged adjacent to the peripheral edge of the bottom 1.

2 indicates a wick of suitable construction which may be arranged withinthe gas or fuel chamber 1 1 indicates a conductor plate or memberextending over the gas or fuel chamber 1.

The plate 1 is preferably of annular shapeand may be integrally formedwith either wall 1. or 1. The plate 1 inclines slightly upwardly fromthe wall to which it is socpred so as to leave an annular space oropening between its lower surface or peripheral edge and the upper edgeof the wall 1, thus forming an annular jet or gas orificc i In themodified form of the invention shown in Figs. 7 and 8 the plate 1 isintegrally connected to the outer wall 1 and extends inwardly andupwardly, forming an annular space or gas orifice 1 between its lowersurface and the upper edge of the wall 1".

In Figs. 1 and 3, which illustrate the preferred form of the invention,the plate '1 is formed integrally with the inner wall 1* and extendsoutwardly and upwardly over the gas or fuel chamber'l. The plate 1serves as a heat conducting element to conduct to the vertical wallwhich supports cooperates with the walls 1*, 1, to form a suitablechamber for the gasification of the fuel so that a gas which will burnwith a blue flame indicating proper combustion without waste or theproduction of undesirable gases, is generated and delivered and burnedat the orifice 1. Extending laterally from opposite sides of thevulcanizer 1 and preferably formed integral therewith, are members 3which permit the vulcanizer 1 to be clamped in operative positionagainst the tire A when it is desired to repair the latter. The members3 are recessed or formed with openings 3 for a purpose to be hereinafterdescribed.

1 indicates means arranged to cooperate with the members 3 to secure thevulcanizer 1 in operative position. Referring to Fig. 3, wherein thevulcanizer is applied to a tire tube A that has been removed from acasing or shoe, the clamping means 4 comprise a base member 45", onwhich the tube A is laid,

, bolts P at its opposite sides arranged to extend through the openings3 of the members 3, and thumb nuts or equivalent devices 4 which, whenscrewed down, engage the members 8 in a Well known manner and efl'ectthe clamping of the vulcanizer -1 in operative position against the tubeA. When it is desired to clamp the vulcanizer l to a tire casing withoutremoving the latter from the wheel, as shown in Fig. 4, the clampingmeans 4: may consist of a chain (not shown) passed around the rim of thewheel, the 0pposite ends of the chain being provided with ,bolts 4adapted to extend through the openings 3 and receive nuts 4.

5 indicates a pair of lugs preferably formed integral with thevulcanizer. 1. These lugs are suitably bored to receive and support athermometer 6 in close proximity to the outer wall 1 and bottom wall 1of the vulcanizer 1, a cap 5 being provided and having screw-threadedengagementwith one of said lugs to hold the thermometer in position. Thelugs 5 are preferably arranged" at the opposite sidesof one of theclamping members 3 in order that the upper surface ofthe latter may, ifdesired, serve as the scale 6 for the thermometer 6.

7 indicates a heat regulator or controller arranged to be mounted on thevulcanizer 1 as will be hereinafter described. The regulator 7 comprisesa frame 7 preferably of skeleton form and provided with a flange 7",

which is adapted to removably engage with the peripheral edge of theplate 1, and a plurality of members 7 depending from the flange 7* anduniformly spaced relatively to each other therearounrh "W hen the frame7 is placed on the vulrn'aizer. 1 as shown in 3, the engagement of theflange 7" with the annular plate 1 serves to maintain the frame 1nposition thereon. The members 7 are of a length to bridge the annularorifice l between the conducting plate 1 and the upper edge of the wall1 and serve to partially close the gas outlet for gas or fuel chamber 1whereby the amount of heat generated by the flames issuing from theorifice 1 is reduced, more of it is radiated before reaching thevulcanizing plate 1, and the temperature of that plate for a shortinterval may be maintained almost constant at the vulcanizingtemperature required. It will of course be understood that the bridgingmembers 7 are of such size that the openings or spaceslbetween them willbe large enough to permit sutlicient air to reach the gas orifice 1 tokeep the flame thereat from being entirely smothered.

ing with the flange 7 b to support the frame 7 in proper position on thevulcanizer 1.

As shown in Fig. 5 the element 7 may be provided with an annular flange7 extend ing in the opposite direction to the serrated flange 7 theflange 7, serving when placed over the jet orifice 1 to put out anyflame at that point.

In operation, the vulcanizer 1 is clamped in operative position againstthe rubber part A to be repaired, a suitable quantity of prepared rubberB to be vulcanized to the part A to eflect the repair being firstproperly positioned between the part A and tlieplate 1", The properamount of fuel, such as gasolene, say a teaspoonful or two, is pouredinto the gas or fuel chamber 1 and the gas issuing through the orifice 1is then ignited, gas being formed in the usual manner. As a result ofthe operation, the walls 1, 1", and

1, soon become heated and through them heat is quickly conducted to thevulcanizing Wall 1 to raise it to the desired degree of temperature, sayfor example, 265 degrees Fahrenheit, at which vulcanization of thematerials used will take place. Substantially the temperature of thewall 1 will be shown by the thermometer 6. When the thermometerindicates that the vulcanizer 1 has been heated to approximately 265degrees F., the heat controller 7 is placed on the vulcanizer 1,as shownin Figs; 3, 4, and 8, and allowed to remain in such position until therepair is completed. The heat controller 7 has the effect ofmaintaiuingthe temperature of the vulcanizer 1: at the deworking ongasolene and the like, the gas .issuing at the orifice 1 burns with ablue flame indicating good combustion. The principal metal parts of-thevulcanizer may be made preferably of aluminum, brass, copper or someother relatively cheap metal of alloy which is a good conductor of heat.The construction of the apparatus is such that it will operatesubstantially the same in any position in which it may be foundnecessary to place it. By confining the flame to a relatively smallannulus the, dangerous and ineflicientcharacteri juice of operation ofvulcanizing devices with open chambers for combustible fluid areavoided. It will be noted that the Walls 1 1 and 1 serve to form a gasor fuel chamber 1 in which the gas collects or is generated and fromwhich it issues at the gas orifice 1 and that this gas orifice 1 isannular in shape so that when the gas is ignited, the flame impingesupon the free'edge of the plate 1 about its periphery. And it will befurther noted that in the preferred embodiment of my in vention heat isconducted by the plate 1 and wall 1 to the central part, the mosteffective part for vulcanizing purposes,of the plate 1*.

To those skilled in the art of making apparatus of the class described,many alterations in construction and widely diifering embodiments andapplications of my inven tion will suggest themselves, without departingfrom the spirit and scope thereof, My disclosures and the descriptionherein are purely illustrative, and are not intended to be in any senselimiting.
